Have a 2001 A6 Avant with standard Concert radio set up. Just out of Audi warranty.

Have experienced major interference/electrical problems with the set - specialist audio engineers have tried to fix twice - but keeps breaking down.

Audi people very unhelpful - no doubt because nothing in it for them. Wont let me have a replacement set for pounds sterling 200 ('because the warranty seals are broken') - have to either have a new one (pounds sterling 700), or pay again to let the 'approved' Audi engineers look at it and give me an estimate to fix.

As the other engineers have confirmed that the build quality of  the set is 'rubbish anyway' and is always likely to keep breaking down, surprise surprise I am now getting a non-Audi decent set from non-Audi retailer (at a further cost to me of over sterling 300 ....)

Two messages - beware Concert radio systems after three eyars, and anyone else who has experienced this nightmare of so called 'quality' parts from so called 'quality' motor manufacturer  - do you have any suggestions????
